DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

FIG. 1 shows in a schematic perspective representation a carrier 3,which is configured in the shape of a square plate. The carrier isarranged in an x-y plane. A peripheral frame 2 is arranged on thecarrier 3. The frame 2 encloses a part space 5 on four sides. In thepart space 5, a part 4 is arranged on the carrier 3. The part 4 isconfigured as an optoelectronic part which can emit electromagneticradiation, in particular visible light. For example, the optoelectronicpart 4 is configured as a laser diode or as a light-emitting diode. Theframe 2 encloses the part space 5, the frame 2 having a frame opening 6which is arranged opposite to the carrier 3. The frame 2 is, forexample, formed from a molding material, for example, epoxy resin orplastic, metal, in particular aluminum.

The optoelectronic part 4 may be configured as a semiconductor chip. Inthe embodiment represented, the part 4 is a square shape. The frame 2comprises an inner frame face 7, which laterally bounds the part space 5peripherally. At least the inner frame face 7 is configured as areflector with a reflection face for the radiation of the part.Depending on the embodiment selected, the entire frame 2 may beconfigured as a reflector. The reflector may, for example, be embodiedby a metallic face, in particular a polished metallic face. The innerframe face 7 extends from the carrier 3 upward to an upper region 8 offrame 2. The upper region 8 is arranged opposite to the carrier 3 on theframe 2.

In the exemplary embodiment represented, the frame 2 comprises fourframe sections 9, 10, 11, 12. The frame sections are respectivelyconfigured as straight frame sections 9, 10, 11, 12 and merge into oneanother in corner regions 13, 14, 15, 16. The frame sections arearranged parallel to an x axis or parallel to a y axis, the x axis andthe y axis being perpendicular to one another. In the exemplaryembodiment represented, the frame 2 comprises four corner regions 13,14, 15, 16, in which in each case two frame sections 9, 10, 11, 12 meetone another at an angle of 90°. Depending on the embodiment selected,the frame 2 may also comprise only three frame sections or more thanfour frame sections. Furthermore, the frame sections may also meet oneanother, or merge into one another, at angles other than 90° in therespective corner regions. Furthermore, the corner regions may also berounded.

The inner frame faces 7 of the frame sections 9, 10, 11, 12 of the frame2, which comprise a reflection face and represent the reflector,essentially comprise an S-shape in cross section perpendicular to thesurface of the carrier 1. The reflection faces of the reflector arereferred to below as inner frame faces 7 of the frame sections.

FIG. 2 shows in a schematic representation a plan view in the y-x planeof a first side face 17 of a lens 18. The first side face 17 of the lens18 has a pyramidal shape. In the example represented, the pyramid isconfigured as a square pyramid with a square base face 19. Furthermore,the pyramid comprises an apex 20 which is arranged at a predeterminedheight from the base face. The square pyramid comprises four lateralfaces 21, 22, 23, 24, which are configured triangularly and converge atthe apex 20. Edges 29, 30, 31, 32 are provided, which separate thelateral faces 21, 22, 23, 24 of the first side face 17 and are orientedstarting from the apex 20 in the direction of the corners of the baseface. Since the base face of the pyramidal shape represents a square,the four lateral faces 21, 22, 23, 24 are configured identically. Thefirst side face 17 of the lens 18 is enclosed by a peripheral edge 25.The lens 18 therefore comprises a first side face 17 with a pyramidalshape, which is enclosed by an edge 25. The lens 18 is made of amaterial which is transparent for the radiation of the part 4, with arefractive index which is greater than that of air. For example, thelens 18 may be made of glass or silicone or epoxy resin or plastic. Theradiation of the part 4 may comprise visible light and/or infraredlight.

The term lens denotes an optically transparent element which causesradiation guiding and radiation directing by refraction and/orreflection, in which case the optical element may comprise an imagingfunction although it does not need to. The term lens is therefore notrestricted to optically imaging elements.

FIG. 3 shows a schematic cross section in an x-z plane through acomponent 1, which comprises a carrier 3, a frame 2 and a part 4according to FIG. 1 , the lens 18 of FIG. 2 being placed onto theopening 6 of the part space 5. In this case, the first side face 17 withthe pyramidal shape protrudes into the part space 5. The lens 18 isplaced with the edge 25 onto the upper region 8 of the frame 2. Thecross section represented passes through the first and third lateralfaces 21, 23 of the pyramidal shape of the first side face 17.Furthermore, the cross section extends through the first and third framesections 9, 11. The apex 20 of the pyramidal shape protrudes into thepart space 5 by a predetermined height H starting from the edge 25. Theinner frame faces 7 of the frame sections 9, 10, 11, 12, which form thereflector, are configured identically in the present example.

In the embodiment represented, the inner frame faces 7 of the framesections, which comprise the reflection faces, in the cross sectionrepresented comprise a face inclined outward starting from the carrier 3in the direction of the lens 18. In this case, the angle of inclinationof the frame faces 7 may be configured in sections differently inrelation to the plane of the upper side of the carrier 3. For example,the frame face 7 may be oriented perpendicularly to the upper side ofthe carrier 3 in a lower first section 26. In a subsequent secondsection 27, the frame face 7 has a radius of curvature and is arrangedinclined outward laterally away from the part 4 and has a convex shape.In a third section, which follows on from the second section 27 and isextended as far as the upper region 8 of the frame 2, the frame face 7has a concave shape. Depending on the embodiment selected, the framefaces 7 of the frame sections may also be configured as faces inclinedoutward.

The lens 18 comprises a first side face 17 with a low pyramidal shape, adistance between the pyramid apex 20 and an upper side 33 of the part 4being less than one third of the height of the part space 5. The heightof the part space 5 denotes the distance between the upper side of thecarrier 3 and the upper side 8 of the frame 2. Depending on theembodiment selected, the lens 18 may comprise a first side face 17 witha larger height. The apex 20 may therefore protrude more deeply into thepart space 5 into a region which is located between one third and onehalf of the distance between the upper side 33 of the part 4 and theupper side 8 of the frame 2.

Depending on the embodiment selected, the lens 18 may comprise furtheroptical guiding structures such as recesses, lens or microprisms on asecond side face 34, which is arranged opposite to the first side face17, in order to achieve additional beam shaping of the electromagneticradiation of the part 4.

In another embodiment, the first side face 17 may have a pyramidal shapewith an even greater height and protrude into the part space 5 by morethan one half, in particular by up to three-fourths, of the distancebetween the upper side 33 of the part 4 and the upper side 8 of theframe 2. Furthermore, depending on the embodiment selected, the pyramidapex 20 may also be arranged even closer to the upper side 33 of thepart 4, and the distance between the apex 20 and the part 4 may be lessthan one third of the distance between the upper side of the part 5 andthe upper side 8 of the frame 2.

FIG. 4 shows a schematic view from above of the component 1 of FIG. 3 ,the lens 18 being represented transparently. The lens 18 is oriented insuch a way that corners of the base face 19 of the pyramid are arrangedover corner regions 13, 14, 15, 16 of the frame 2. The edges 29, 30, 31,32, which separate the lateral faces 21, 22, 23, 24 of the first sideface 17, are therefore aligned in the direction of the corner regions13, 14, 15, 16 of the frame 7. The base face 19 of the pyramid ispreferably configured to be so large that at least 50%, in particular75% or more of the area of the opening 6 is covered with the base face19. For example, the base face 19 may cover more than 90%, in particularmore than 95%, of the area of the opening 6. In this way, efficientradiation guiding is achieved.

In the configuration of a frame 2 with three corner regions, thepyramidal shape also comprises only three lateral faces and three edges.In this embodiment as well, the edges and therefore the corners of thebase face 19 of the pyramid are oriented in the direction of the cornerregions of the frame. If the frame comprises more than four cornerregions, then the lens 18 also has a pyramidal shape with a base face 19with more than four corners, and therefore with more than four lateralfaces and more than four edges. In this embodiment as well, in each casea corner of the base face of the pyramid and therefore an edge isoriented in the direction of a corner region of the frame 2.

FIG. 5 shows a perspective representation of another embodiment of acarrier 3 with a frame 2 and a part 4. The frame 2 is formed from fourframe sections 9, 10, 11, 12 and is constructed essentially according toFIG. 1 . However, the shape of the frame faces 7 of the frame sections9, 10, 11, 12 differs from the embodiment of FIG. 1 . Furthermore, thefirst and third frame sections 9, 11 are configured to be longer thanthe second and fourth frame sections 10, 12. The first and third framesections 9, 11 are configured with equal length. The second and fourthframe sections 10, 12 are configured with equal length. The frame 7 withthe four frame sections therefore delimits a rectangular part space 5.

FIG. 6 shows in a cross section another embodiment of a lens 18, whichcomprises as a first side face 17 a pyramidal shape according to thelens 18 of FIG. 2 , although the apex 20 is further away from the baseface, or the frame 25, than in FIG. 2 . Furthermore, the lens 18comprises a rectangular base face.

FIG. 7 shows a component 1 which comprises the frame 2 with the carrier3 and the part 4 according to FIG. 5 and the lens 18 according to FIG. 6. The lens 18 protrudes with the first side face 17 and with the pyramidapex 20 closer to the upper side 33 of the part 4. Furthermore, thefirst and third frame sections 9, 11, represented in cross section, havea different shape than the frame sections of the embodiment of FIGS. 1and 3 . In the embodiment represented, the frame face 7 of the framesections 9, 11 is divided into a first and a second section 26, 27. Thefirst section 26 meets the upper side of the carrier 3 and is configuredperpendicularly. The first section 26 extends to above the upper side 33of the part 4. The second section 27 of the frame face 7 extends fromthe first section 26 to the upper side 8 of the frame 2. The secondsection 27 is configured as a curved concave face.

Depending on the embodiment selected, the lens 18 may comprise opticalguiding structures such as recesses, lenses or microprisms on a secondside face 34, which is arranged opposite to the first side face 17, inorder to achieve additional beam shaping of the electromagneticradiation of the part 4.

FIG. 8 shows a schematic plan view of the component 1 of FIG. 7 , therectangular lens 18 and the frame 7 with the frame sections 9, 10, 11,12 being represented. The first and third lateral faces 21, 23 are ofequal size. The second and fourth lateral faces 22, 24 are of equalsize.

FIG. 9 shows a cross section in the z-x plane through the component 1 ofFIGS. 7 and 8 . It can be seen in this case that the radiation field,which is emitted from the upper side 33 of the part 4, can be dividedinto two regions 35, 36, the two regions 35, 36 being represented asseparated by an imaginary separating line 38. In the first region 35,the rays are emitted directly into the first side face 17 of the lens18. In the second region 36, which is formed between the first region 35and the frame 2, the electromagnetic rays are first emitted, startingfrom the upper side 33 of the part 4, in the direction of the innerframe face 7, are reflected by the inner frame face 7 and are directedin the direction of the first lateral face 17 of the lens 18.

FIG. 10 shows a cross section through the component 1 of FIGS. 7 and 8in the z-y plane. The part space 5 comprises a rectangular face and isconfigured longer in the y direction than in the x direction. In asimilar way, the angle of inclination of the lateral faces of thepyramidal shape of the first lateral face 17 of the lens 18 is smallerfor the first and third lateral faces 21, 23 than for the second andfourth lateral faces 22, 24. In this case as well, the radiation fieldwhich is emitted from the upper side 33 of the part 4 can be dividedinto two regions 35, 36, the two regions 35, 36 being represented asseparated by an imaginary separating line 38.

FIG. 11 shows in a perspective representation a plan view of the firstlateral face 17 of the lens 18 of FIG. 6 . The first lateral face 17 hasa pyramidal shape with a rectangular base face 19. The first and thirdlateral faces 21, 23 and the second and fourth lateral faces 22, 24 arerespectively configured identically. However, the shapes and areas ofthe first lateral face 21 and of the second lateral face 22 differ.

FIG. 12 shows a plan view of the first side face of the lens 18 of FIG.10 .

Depending on the embodiment selected, the first side face 17 of the lens18 of FIG. 2 or FIG. 6 may also have a pyramidal shape with a base face20 with five corners and therefore with five lateral faces, as isrepresented in FIG. 13 .

Furthermore, the first side face 17 of the lens 18 of FIG. 2 or of FIG.6 may also be configured in the shape of a partial pyramid, particularlyin the shape of a pyramidal frustum, as is represented in FIG. 14 . Thepyramidal frustum comprises a rectangular base face 19. In thisembodiment, the first side face 17 comprises four lateral faces 21, 22,23, 24 and one top face 37. The top face is likewise configuredrectangularly. The lateral faces 21, 22, 23, 24 are configured astrapezoidal faces in this embodiment. The top face 37 is arrangedparallel to the base face 19. In the embodiment represented, the baseface 19 comprises four corners, and the pyramidal shape therefore alsocomprises 4 four edges 29, 30, 31, 32. The base face 19 of the pyramidalfrustum is preferably configured to be so large that at least 50%, inparticular 75% or more of the area of the opening 6 is covered with thebase face 19. For example, the base face 19 may cover more than 90%, inparticular more than 95%, of the area of the opening 6. In this way,efficient radiation guiding is achieved.

Depending on the embodiment selected, a lens 18 with a first side face17 which comprises a pyramidal frustum according to FIG. 14 may also beprovided, but with the base face 19 being configured squarely. In thisembodiment, the top face 37 is also configured squarely.

Furthermore, depending on the embodiment selected, in the configurationof the first side face 17 of the lens 18 in the shape of a pyramidalfrustum, both the top face 37 and the lateral faces 21, 22, 23, 24 mayhave a rounded shape, in particular a concave or convex shape.

FIG. 15 shows a cross section through the top face 37 of the first sideface 17 of the lens 18 of FIG. 14 , the cross section being arranged ina z-x plane. The top face 37 is arranged in a y-x plane. In thisselected embodiment, however, the top face 37 comprises bending in the zaxis along the y axis.

FIG. 16 shows a cross section through the top face of FIG. 14 in the z-yplane. The top face 37 also comprises a curvature in the direction ofthe z axis along the y axis. Depending on the embodiment selected, theradii of curvature of the top face 37 along the x axis and along the yaxis may be of equal size or different sizes.

In a similar way, the lateral faces both of a first side face 17 in theshape of a pyramidal frustum or of a first side face 17 the shape of apyramid may be configured as convex or concave faces and comprise acurvature.

FIG. 17 shows a cross section through lateral faces 21, 22, 23, 24 of apyramidal frustum of FIG. 14 in a y-x plane which is arranged parallelto the base face 19. In this case, it can be seen that the lateral faces21, 22, 23, 24 respectively comprise a curvature, that is to say acurved surface outward in the x-y plane.

The first side face 17 of a lens 18 both in the shape of a pyramidalfrustum and in the shape of a pyramid may therefore comprise facesrounded both in planes parallel to the base face 19 and in planesperpendicular to the base face 19. The curvature of the side faces, inparticular the convex curvature, should be dimensioned at most to be solarge that the light rays from each emission region of the part candirectly strike a transition region between the side face and the edgeof the first side face.

An angle of inclination of a plane lateral face 21, 22, 23, 24 may bebetween 1° and 45°. For example, the lateral faces may be oriented at anangle of 15° with respect to the base face 19. A part may comprise anupper side 33 which is, for example, between 500 μm and 1 mm long andwide. The part may have a height which is in the region of 1.6 mm. Thereflector may have an overall height which, for example, is in theregion of 0.8 mm.

The rays reflected by the first side face 17 of a lens 18 are reflectedexternally onto the reflector and do not leave the component withoutdeviation. Furthermore, the electromagnetic radiation emitted by thepart directly strikes the reflector, that is to say the reflective innerframe face 7. The electromagnetic rays striking the inner frame face 7are reflected in the direction of the first side face 17 and refractedby the first side face 17 uniformly in the direction of the opticalaxis.

Because of the frustopyramidal shape or the pyramidal shape, thereflector can be configured to be flat, that is to say the inner frameface 7 may have a relatively small height. In this way, a very flatreflector design is possible. Furthermore, high beam strengths andnarrow-angle emission with a square or rectangular emission geometry canbe achieved. Furthermore, because of the proposed components, animproved efficiency is achieved by more effective use of the raysreflected by the lens structure. The proportion of light not deviatedinto the optical axis is thereby reduced.
